ALFRED GILBERT BROWN, OF EGAN, DAKOTA TERRITORY.

DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 403,873, dated May 21,1889.

' Application filed January 3, 1889- $erial No. 295,299. (No model.)

To all whom it may concern.-

Be it known that LALFRED GILBERT BROWN, a citizen of the United States,residing at Egan, in the county of Moody and Territory of Dakota, haveinvented certain new and useful Improvements in the Method of andApparatusfor Equalizing Draft; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference beinghad to the accompanying drawings, and to theletters and figures of reference marked thereon,which form a part ofthis specification.

My invention relates to an improved method of and apparatus forequalizing draft, whereby an effective equalization of the traction isproduced where the power is unequally divided on the respective side ofthe vehicle pole or shaft; and it consists in the method and arrangementof parts hereinafter described, and definitely pointed out in theclaims.

The object of my invention is to provide a simple, effective, andconvenient means for equalizing draft and distributing the stress on theseveral members of the attached portions of the vehicle. I attain thisobject by the device and construction illustrated in the accompanyingdrawings, wherein like letters of reference indicate corresponding partsin both views, and in Which Figure 1 represents a plan view of myequalizer as attached to a vehicle-pole, and Fig. 2 a detail view of theequalizer.

In the drawings, A represents the vehiclepole, and B B B the whifiietrees, attached, respectively, to the long arms of levers O and O. Thelever O is fulcrumed on the end of a rod or arm, D, placed parallel withthe pole, its lower end being pivot-ally secured to a cross-bar, D,whichis pivoted at its center to the pole and extends out on either sidethereof.

The short arm or inner end of the lever C is pivotally secured to theend of a diagonallyarranged brace-rod, E, which extends beyond thecross-bar D, its upper end being adjacent to the side of the poleopposite that of the lever C. To support and retain this brace E inplace, a bar or brace, F, is placed parallel with the inner end of thelever O and rigidly secured to the pole, its end being provided with asupport or guide-plate, F, at the side of the pole below the lever O,for assisting in supporting the same. To the opposite end of thecross-bar D is pivoted an arm, D extending forward and parallel with thearm D, its upper end forming afulcrum for the lever O,which is shorterthan the lever C, its short arm being pivotally secured to the end oflever 0 and brace E.

G represents a laterally-arranged crossbar centrally secured to the poleback of the crossbar D. The inner end of brace E is secured to one endof this cross-bar G, and the end of an oppositely obliquely-arrangedbrace, H, is secured to the opposite end, the forward end of this braceH being secured to the pole at the pivotal point of the cross-bar D. Tomore effectively resist and equalize the stress on the brace andcross-pieces, I secure a parallel brace-strip, K, to the cross-pieces Dand G.

By the above arrangement and construction it will be noticed that agradual and regular distribution of the draft is secured, the locationand arrangement of the several members being such as to avoid the usualre sults of all sudden jerks and vibrating movements of the power, andthe back-pressure obtained from the main levers obviates side draft andsteadies the pole.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

l. The draft equalizer herein described, consisting of the levers O andO, the diagonal brace E, the cross-bars D and G, the parallelfulcrum-arms D and D and the braces H and K, substantially as described.

2. In a draft-equalizer, the combination, with the pole, of the levers Oand O, the fulcrum-arms D and D the cross-bar D ,the diagonally-arrangedbrace E, the bar F, having plate F on its end, the cross-bar G, and thebraces H and K, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ALFRED GILBERT BROWN.
